Xiaomi Smart Camera C400

The Xiaomi Smart Camera C400 is a modern indoor security camera designed to provide high-quality surveillance with ease of use and versatile installation. Equipped with a 4-megapixel lens and 6P optics with an f/1.4 large aperture, it captures video at 2.5K resolution (2560 × 1440), delivering sharp, detailed imagery even in low-light conditions. Whether it’s daytime or nighttime, the footage remains clear and realistic.

What sets C400 apart is its full 360° horizontal rotation and 106° vertical panning capability, powered by a dual-motor pan–tilt mechanism. This provides complete room coverage without blind spots — ideal for living rooms, offices, or any indoor space you wish to monitor thoroughly. Night vision uses 940 nm infrared light without visible red glow, ensuring discreet and non-disruptive surveillance at night.

The camera features built-in microphone and speaker for real-time two-way voice communication. You can listen to your space and speak through the camera via the companion app — a strong advantage for baby monitoring, pet check-ins, or household communication. Thanks to smart noise reduction, audio remains clear even in noisy environments. The device connects over dual-band Wi-Fi (2.4 / 5 GHz), ensuring stable and fast connectivity. Additionally, you can store recordings locally on a microSD card (up to 256 GB) or via cloud storage if offered — giving flexibility in video archiving and playback. 

For installation, you can place the C400 on a flat surface like a table or desk, or mount it on a wall or ceiling using the included mounting kit. Its flexible setup and user-friendly design make it convenient for home use without hassle. 

In summary, the Xiaomi Smart Camera C400 combines high-resolution video, full-area coverage, smart monitoring features, and two-way audio — making it an excellent choice for anyone looking for reliable, easy-to-use indoor surveillance for their home, family, or belongings.
